Same. I wish he would rather go by explaining and mostly showing them even what happens when things don't add. I mean the Adapter class or etc, that he used in his code. So that, it at least makes sense why things needed to be written.
Its not complex, its dumb. Design patterns should not be used for every possible piece of code. Mainly the java people are to blame for bringing this garbage onto the world. Most people are fed up with it and this is why languages like Go and Rust are on the rise.
In my opinion it would be more educational, if you showed how the app works part by part in the emulator instead of coding everything at once and showing the end result just at the end. Otherwise, very good tutorial!
A couple of things that helped me understand this video a bit better: 1) doing the fella's crash course and building a couple of command line apps 2) don't copy exactly what he is doing. Make an app with a similar concept (e.g. an app a waiter would use to note down food / drink orders) change the variable names and the names of the files, this way you have to figure out what is going on. The more different you can make it while keeping the same basic elements, the more it will make sense to you after building it
This has always given me the best results. nothing like typing all of this out but not *really* knowing why. By taking your suggestion, you can begin to connect the *why* dots on all of these concepts.
Great video! at the minute 47:12, my editor does not detect the tvTodoTitle nore cbDone objects defined in the item_todo.xml, because of this I cannot complete the apply function. Any idea about what I missed? (I am an absolute beginner)
I don't know why, but I feel like android development is extremely complex unnecessarily compared to web development. You have to write so much code to print so little.
You are completely correct. I had the same feeling. Android is unnecessarily complex, with too much OOP, hexagonal architecture, and so on just to do a simple screen...
You dont really explain what a lot of the functions do after the half point of the video. Theres also a major issue at 47:40 where you cant continue to follow along because it wont let you link tvTodo and the other var
omg, let me be honest. Classes seem to overcomplicate things that shouldn't be. I have been doing functional programming, my mind switched off after 40:00, Why do you need a separate class for every goddamn thing? It just complicates things. How do you learn what class inherits from what class? It is just a simple todo list for God's sake... I am just typing along without understanding shit. I worked with classes, but isn't this a bit overkill?
@@Dinesh_Great yes, you need to go to your "build.gradle module: app" file where you will find a plugins block on top. In this plugins block, you simply paste this line and click on sync now: id 'kotlin-android-extensions'
had to give up near the end because apparently we have slightly different versions of the IDE and I couldn't solve a step... i wouldve liked a bit more explanation of each step tbh so i understood what was being done and what other options there were
My version of Android Studio produces a different default app with no LAYOUT folder/files and uses COMPOSABLE functions. So I'm totally baffled at the moment...
Thank you for actually teaching stuff Most beginner tutorials out there just go all in expecting people to know how Android Studio's styling works even when they're aimed at beginners and i've watched half of the video so far and i'm understanding everything EDIT: Nevermind, i lost all track of anything once he got over the styling and i already know other programming languages well

If I may… Thanks for the course, you really put a lot of work in this. But (sorry for that part) if I learned something in almost 40 years of coding it is that a beginner tutorial should always be done by a (almost) beginner! You clearly know what you are talking about but you lost almost everyone trying to explain too many different concepts while rushing some others. Android Studio is not a tool that can be mastered through a single course, especially if you don’t know Java, one of the hardest coding language still around (not JavaScript which is a breeze in comparison). An AS beginner course should probably be more focused on the interface, some basic code and a lot of visual stuff to set your interface up as well as a simple way to test your very basic app on a device, because that is the reward beginners are looking for. Anyway, as I said nice effort.
This is too hardcore for me now. Need to find something easier. For example the override functions for Recycle view and their arguments, I don't have a clue about what, why, where, how. Completely lost on this part.
If you're just getting into android dev and this video confused you like it did me, its because this is not the default way to make UIs in android anymore. The thing now apparently is to use jetpack compose to create your UI entirely through kotlin instead of using XML.
Jesus. Why is everything so complicated in Android Studio? Couldn't they just do it the less-cluttered style? All that xml data are almost the same. They should be automatic and the design, ugh. Very ugly implementation.

Man, Android development sure looks inaccessible with development tools this fucking unstable/unreliable xD
Just can't imaging how back in times ppl developed Android apps in Java. Must be cried a lot. Android is not Java-based, it's Linux-based that supports JDK to write Android app. Kotlin does not belong to Google, it's being developed by JetBrains company, the one which created IntelliJ, ReSharper, Android Studio and other cool products. Kotlin is not based on Java, it's JVM compatible, that allows it to be used for Android apps too along with Java. Cobol is still alive, Fortran is still alive. I bet Java will be 'dying' next 50 years.
Does anyone has a problem that Android Studio not let you import tvTodoTitle? Maybe someone can help me in this situation. I've tried to write it by hands, but it didn't work.
Just found out after debugging for 1 hour: the solution is described in the pinned comment. You need to add "id 'kotlin-android-extensions'" in your Gradle file
I ran into trouble with this because the synthetic view binding is deprecated shown in this video... @Phillipp Lackner if you could update a new one with this or Jetpack it would be much appreciated! FWIW, I got this to work with viewbinding :)
Next time you make a video can you please say 5 times less words? Be short. Just say this: "Step 1. Create a view.". "Step 2. Set constraints". Don't give an endless stream of words
Hello thanks for this great tutorial :-) I was thinking what about making a part two, where we make it so the app can save data even after we close and reopen it ?
Because web development deals with a bunch of abstractions so you dont actually deal with many Computer Science concepts. Android development falls into the category of native development, which is far more complex than web development. Without native development, the components and tools that web development leverages wouldn't exist. In short, web development is very straightforward because most of the complexity has been handled by native developers
I’ve used and developed for both Android and iOS, and as a result, I’m not really biased. They are both good in their own ways. However, i will admit, because iOS has a proprietary language (Swift, SwiftUI or Objective-C and UIKit) it is SO much easier to develop an app, java and kotlin is very complex to me. Swift has a relatively straightforward syntax.
hey devs, having problem 47:40? add this to your build.gradle(:app) id 'kotlin-android-extensions' I dont know why youtube always remove may detailed instruction on this :( plugins { id 'com.android.application' id 'kotlin-android' id 'kotlin-android-extensions'
Hi, this didn't work for me, still having issues with it finding the tvTodoTitle TextView. Any other suggestions? I think a few people are having the same issue.
You lost me.. when u started your todo class.. pick some simpler topic... for example Adding two number from two different text box and showing them in a textview on click of a submit button. Next could be concatenate two textbox and on clicking submit button the output will be displayed in a Textview.. This is way too complex for beginners. Will keep a watch on your channel for beginners video.
I wish they will eventually do all the heavy lifting with adding all these extra stuff in the layout building so we can just focus on code. Thats too much information to absorb just to build layout
Philipp, do you plan to make a video showing how to connect this todo list with a database so that items that are added to the list are retained when the app is closed and reopened?
apply plugin: 'kotlin-android-extensions' in the build.gradle is depricated. So the elements from the activity are unknown. Could you show how to fix it? I tried the reference from google but it didn't work. Writing the parameters under each other is very bad to read. You can't tell if it's the passing parameters or the code in the function.
Found the solution further down in the comments, make sure the sync the project by either right clicking "kotlin-android-extensions", then Actions (first option) and it should have sync as an option. Alternatively you should be able to sync it in the blue bar just below the tabs.
Ok thank you for helping but it was hard understanding what you were trying to say. I still went through the whole video but if you could explain more of the parts in depth, that would help my understanding by a mile. Thank you for the video!
Philipp the way your explaining the cours is so fast and hard for beginners as me to fallow with you but good look I'm going to check your channel for more videos thanks
Hi Sir, Thank you for the video, after going through the video i have some problem in "onBindViewHolder" i am couldn't able to get the details of tvToDoTitle, cbDone details from item_todo.xml, please let me know do i need to import any specific lib, currently i am following as shown in video.
Hey I also had a lot of trouble with this and after quite a while of troubleshooting I found something that works, I could however not get the strike through to work properly... But here's what worked for me after setting "buildFeatures { viewBinding = true }" in android {} and adding "id 'kotlin-parcelize'" to plugins {} in build.gradle Module: first do this outside onBindViewHolder: private lateinit var binding: ItemTodoBinding Then inside onBindViewHolder do: binding = ItemTodoBinding.bind(holder.itemView) And then when calling the tvTodoTitle add "binding." infront of cbDone and tvTodoTitle
Why is Android development overly complicated and over-engineered? Why can't it be easier like web development or backend development? Unnecessarily weirdly named classes and functions make even simple tasks feel like coding for a missile navigation system. I'd rather write a full-stack web app from scratch in C (a custom frontend UI library written in C, database, and RESTful API) than writting Android development.
Java has taken a big leap since this video. Look at Java 21 and 22. Many new features to Java. I'm looking forward to Kotlin supporting these new features, they only support some features in JDK21 as of Kotlin2.0.0
A word of advice for anyone trying to teach coding of ANY language. It's fair enough to do a video and try to explain the code. You should ALWAYS COMMENT your code regardless as when you go back to look at it, especially when learning the language or coding for the first time, having comments that will identify what the code is doing is a huge help. This is industry standards and should be used. There are several reasons, one is to remind you of the code (please do not think you will remember every line of code, where it points to in all the programs you work on, as you may well NOT work on EVERY part of a program), secondly, someone else having a look that is allowed to, to may be help with issues, or, come in fresh because you left for another job, as some examples, will need to be able to see what the code is for and what it is doing. You should get into the habit of commenting as you go OR, better still, comment that code before actually coding as this helps you plan your code better.
Also, don't make paragraphs, use short simple comments. Also, though not for this video but as a golden rule to know, when ever you create an application, database that may run alongside (full stack) or standalone, check if your country has automatic copyright. Designs may need to be registered or may not. This comes under Intellectual Property. IF you do not want someone using your code then DO NOT post it publicly. This video is for learning so that's fine, but, for real applications, check your country's copyright laws and if they apply automatically and at the top of each class, like with C# using the /// (comments vary so check) stick in there the copyright and who it belongs to and which country, whether it is automatic, date and that any copying, reuse or whatever is strictly by requesting permission to use the code. Keep the paper trail, this could prove vital if someone steals your code DO NOT share what you do not want people using. Boiler plate code? it's boiler plate and doesn't really refer to any program and boiler plate code is freely available. There is International Copyright acceptance and recognition between countries and anyone from another country using your code can be liable to a law suit if proven to be falsely claiming your code. Many countries have automatic copyright such as Barbados and the UK, not all but many do. Places like Github can be private or public. Check GPU Licence (general Public and can be used and modified) and EULA (End User Licence Agreement which is NOT public and can not be used and modified). Get in the habit as it could save you in lots of ways.
Thanks Phillip you done a great job, but like always Google is full of PhD's who can't tie their own shoes or anyone elses!!! They need to learn something from Microsoft. Long live Visual Studio and C# and Easy GUI development! Way too complex for something that could be much much easier.
this is why i dont like java there are so many objects that are interrelated... and then what is that weirdness when you access a class's field or (maybe properties) you can access another functionality.. so many weirdness in this language.. i suspect when one day nobody needs to code anymore because the compiler already know what to do .. we just prepare the xml files and the image file
Hi Philipp.. I tried this code by following each steps and it's a success. How can I convert it to an App and how Can I load it to my android phone? Thanks for the videos, it's very useful.
Sorry, but this was just and "do stuff" tutorial without me understanding what is happening. I know that apps involving views are not that easy to understand, but this video didn't help me either.
So, I like your effort Philipp. What I didn't like is you skipped over the exception messages, and reiterated the same in your words. I feel this is being a bit dishonest. I would rather teach somebody to drive the car, rather than showing them how I'm driving the car. Also, I don't think this an 1 h 11 minute long content.
ok, i did exactly how you did but once i write tvTodoTitle (47:18) it just doesn't find it and neither cbDone or the other items in item_todo.xml. don't know what to do i literally don't understand nothing about android development.
hey devs, having problem 47:40? add this to your build.gradle(:app) id 'kotlin-android-extensions' I dont know why youtube always remove may detailed instruction on this :( plugins { id 'com.android.application' id 'kotlin-android' id 'kotlin-android-extensions'
Just a tip: take pauses between thoughts and sentences. It’s okay to give the listener time to digest the information, and would help you gather your thoughts for more articulate and meaningful delivery.
In regards to my question about a possible future tutorial on how to link this with a database: Would you be able to direct me to a tutorial that would show how to link a database with the code you've written in this app so that list inputs would be retained when app is exited & reopened? It would be much appreciated. Thank you.
Love your teaching style. Easy to follow for someone like me who is such a newbie to coding. One question: I followed the tutorial and it came out fine except that the list wouldn't retain the entries. However, I did not do this as a standalone app - I added the todo list as an activity to an existing app I'm making. Would that be the reason the entries disappeared once I closed the activity and went to another page? Maybe there's a bit of extra code I'm needing? Thanks again for the tutorial. Really helpful for a 50+ lady like me who's such a rookie

Be short. Just say this: "Step 1. Create a view.". "Step 2. Set constraints". Don't give an endless stream of words
Hello thanks for this great tutorial :-)
I was thinking what about making a part two, where we make it so the app can save data even after we close and reopen it ?
Because web development deals with a bunch of abstractions so you dont actually deal with many Computer Science concepts. Android development falls into the category of native development, which is far more complex than web development. Without native development, the components and tools that web development leverages wouldn't exist. In short, web development is very straightforward because most of the complexity has been handled by native developers
I’ve used and developed for both Android and iOS, and as a result, I’m not really biased. They are both good in their own ways. However, i will admit, because iOS has a proprietary language (Swift, SwiftUI or Objective-C and UIKit) it is SO much easier to develop an app, java and kotlin is very complex to me. Swift has a relatively straightforward syntax.
Hello,
I have issue tvToDoTitle and cbDone class. I am using MAC. any solution? I am not able to import tvToDoTitle and cbDone class
Doesnt let me import the btnDeleteDone todos at 1:02:31
hey devs, having problem 47:40? add this to your build.gradle(:app) id 'kotlin-android-extensions'
I dont know why youtube always remove may detailed instruction on this :(
plugins {
id 'com.android.application'
id 'kotlin-android'
id 'kotlin-android-extensions'
thanks
Hi, this didn't work for me, still having issues with it finding the tvTodoTitle TextView. Any other suggestions? I think a few people are having the same issue.
You lost me.. when u started your todo class.. pick some simpler topic... for example Adding two number from two different text box and showing them in a textview on click of a submit button. Next could be concatenate two textbox and on clicking submit button the output will be displayed in a Textview.. This is way too complex for beginners. Will keep a watch on your channel for beginners video.
nice hair bro
Android Extensions is deprecated. How do I import item_todo.xml for onBindViewHolder?
I can't import a tvTodoTitle ... why any ideas?
I wish they will eventually do all the heavy lifting with adding all these extra stuff in the layout building so we can just focus on code. Thats too much information to absorb just to build layout
exactly. Very cluttered and it's built like we're still in the middle ages.
Philipp, do you plan to make a video showing how to connect this todo list with a database so that items that are added to the list are retained when the app is closed and reopened?
apply plugin: 'kotlin-android-extensions' in the build.gradle is depricated. So the elements from the activity are unknown. Could you show how to fix it? I tried the reference from google but it didn't work.
Writing the parameters under each other is very bad to read. You can't tell if it's the passing parameters or the code in the function.
I'm not getting the message that it's deprecated but it doesn't work for me either, please let me know if find a solution cheers.
Found the solution further down in the comments, make sure the sync the project by either right clicking "kotlin-android-extensions", then Actions (first option) and it should have sync as an option. Alternatively you should be able to sync it in the blue bar just below the tabs.
Its like java script on the outside and python inside of the curly brackets fml :)
Any web developers just watching this video?
Quick question:
On 47:40 how can I import tvTodoTitle and dbDone? Mine is to importing it.
Thanks
Same issue.
I understood nothing from programming part, what is going with all those class inheritance, class type, etc
Same
Ok thank you for helping but it was hard understanding what you were trying to say. I still went through the whole video but if you could explain more of the parts in depth, that would help my understanding by a mile. Thank you for the video!
Philipp the way your explaining the cours is so fast and hard for beginners as me to fallow with you but good look I'm going to check your channel for more videos thanks
Thanks very helpful . Just one criticism. The dark background makes it almost impossible to read the code from the screen.
47:57 I didn't get any 'Import' option after clicking Alt+Enter. What could be the reason?
did you figure it out? I'm having this problem too
I'm not familiar with kotlin but seems too confusing to have a nested class and even to have a parent class type of its nested class.
When i am trying to access the variables of item_todo.xml in adapter class its showing error? Can anyone please help?
48:19 showing errors in text and ischecked why?
The binding method here is deprecated.
Hi Sir, Thank you for the video, after going through the video i have some problem in "onBindViewHolder" i am couldn't able to get the details of tvToDoTitle, cbDone details from item_todo.xml, please let me know do i need to import any specific lib, currently i am following as shown in video.
Hey I also had a lot of trouble with this and after quite a while of troubleshooting I found something that works, I could however not get the strike through to work properly...
But here's what worked for me after setting "buildFeatures { viewBinding = true }" in android {} and adding "id 'kotlin-parcelize'" to plugins {} in build.gradle Module:
first do this outside onBindViewHolder:
private lateinit var binding: ItemTodoBinding
Then inside onBindViewHolder do:
binding = ItemTodoBinding.bind(holder.itemView)
And then when calling the tvTodoTitle add "binding." infront of cbDone and tvTodoTitle
Have you found a solution for the error? I got the same thing smh
@@JustAbdouIt any solution to this?
Bro has brains all over that hair. Great tutorial btw 🔥
at 46:54 apply function is not loading in view class??
i am having trouble importing the tvTodoTitle in the curTodo can anyone helpe me? its on 47:40
me too
rez
I just want to know if you are storing your todos in a database or not?? Or how does the storing work, I'm quite confused...
Why is Android development overly complicated and over-engineered?
Why can't it be easier like web development or backend development?
Unnecessarily weirdly named classes and functions make even simple tasks feel like coding for a missile navigation system.
I'd rather write a full-stack web app from scratch in C (a custom frontend UI library written in C, database, and RESTful API) than writting Android development.
47:40 Isn't working in 2023
Oh thankfully it's not only for me. Any solution for this/
Java has taken a big leap since this video. Look at Java 21 and 22. Many new features to Java. I'm looking forward to Kotlin supporting these new features, they only support some features in JDK21 as of Kotlin2.0.0
A word of advice for anyone trying to teach coding of ANY language. It's fair enough to do a video and try to explain the code. You should ALWAYS COMMENT your code regardless as when you go back to look at it, especially when learning the language or coding for the first time, having comments that will identify what the code is doing is a huge help. This is industry standards and should be used. There are several reasons, one is to remind you of the code (please do not think you will remember every line of code, where it points to in all the programs you work on, as you may well NOT work on EVERY part of a program), secondly, someone else having a look that is allowed to, to may be help with issues, or, come in fresh because you left for another job, as some examples, will need to be able to see what the code is for and what it is doing.
You should get into the habit of commenting as you go OR, better still, comment that code before actually coding as this helps you plan your code better.
true explain the code and illustrte to be more clear but you tried.
Also, don't make paragraphs, use short simple comments. Also, though not for this video but as a golden rule to know, when ever you create an application, database that may run alongside (full stack) or standalone, check if your country has automatic copyright. Designs may need to be registered or may not. This comes under Intellectual Property.
IF you do not want someone using your code then DO NOT post it publicly. This video is for learning so that's fine, but, for real applications, check your country's copyright laws and if they apply automatically and at the top of each class, like with C# using the /// (comments vary so check) stick in there the copyright and who it belongs to and which country, whether it is automatic, date and that any copying, reuse or whatever is strictly by requesting permission to use the code. Keep the paper trail, this could prove vital if someone steals your code
DO NOT share what you do not want people using. Boiler plate code? it's boiler plate and doesn't really refer to any program and boiler plate code is freely available. There is International Copyright acceptance and recognition between countries and anyone from another country using your code can be liable to a law suit if proven to be falsely claiming your code. Many countries have automatic copyright such as Barbados and the UK, not all but many do.
Places like Github can be private or public. Check GPU Licence (general Public and can be used and modified) and EULA (End User Licence Agreement which is NOT public and can not be used and modified).
Get in the habit as it could save you in lots of ways.
Thanks Phillip you done a great job, but like always Google is full of PhD's who can't tie their own shoes or anyone elses!!! They need to learn something from Microsoft. Long live Visual Studio and C# and Easy GUI development! Way too complex for something that could be much much easier.
My head exploded in the TodoAdapter >_< I'll better go back to basics
this is why i dont like java there are so many objects that are interrelated...
and then what is that weirdness when you access a class's field or (maybe properties) you can access another functionality..
so many weirdness in this language..
i suspect when one day nobody needs to code anymore because the compiler already know what to do ..
we just prepare the xml files and the image file
Hi Philipp..
I tried this code by following each steps and it's a success.
How can I convert it to an App and how Can I load it to my android phone?
Thanks for the videos, it's very useful.
You'd just need to export it to an APK
or you could use android Debugger/Developer Mode in you android phone
but it does not port the app
Sorry, but this was just and "do stuff" tutorial without me understanding what is happening. I know that apps involving views are not that easy to understand, but this video didn't help me either.
Why does it have to be so complex? Isn't there any simpler way to do this?
No. Welcome to progress.
Flutter Dev be like
"Look What They Need To Mimic A Fraction Of Our Power"
Awesome, simple tutorial yet have the full features of a todo app. can't wait to try it.
So, I like your effort Philipp. What I didn't like is you skipped over the exception messages, and reiterated the same in your words. I feel this is being a bit dishonest. I would rather teach somebody to drive the car, rather than showing them how I'm driving the car.
Also, I don't think this an 1 h 11 minute long content.
ok, i did exactly how you did but once i write tvTodoTitle (47:18) it just doesn't find it and neither cbDone or the other items in item_todo.xml. don't know what to do i literally don't understand nothing about android development.
hey devs, having problem 47:40? add this to your build.gradle(:app) id 'kotlin-android-extensions'
I dont know why youtube always remove may detailed instruction on this :(
plugins {
id 'com.android.application'
id 'kotlin-android'
id 'kotlin-android-extensions'
it must be the most popular tutorial on android sdk, cuz gemini fills all the code on Tab like its reading my mind, or see youtube video
okey, I must spend whole day to program simple list view gadget population function with logicless constructions.
Just a tip: take pauses between thoughts and sentences. It’s okay to give the listener time to digest the information, and would help you gather your thoughts for more articulate and meaningful delivery.
This is why we should have kept the dislike button, what a waste of time. The tutorial just gives up half way through.
Cant you make the app save the list in a local txt file and then read that for the next time you open the app?
For a saving system?
In regards to my question about a possible future tutorial on how to link this with a database: Would you be able to direct me to a tutorial that would show how to link a database with the code you've written in this app so that list inputs would be retained when app is exited & reopened? It would be much appreciated. Thank you.
That's the longest video I have ever watched without skipping
with MVVM?
No
😂
Lmao
can you please make video for Coroutine and flow with kotlin in your youtube channel That would be great! Please
bnaya kya fir humne ??
what are we making please mention the name of the App I dont have Time to Waste
Love your teaching style. Easy to follow for someone like me who is such a newbie to coding. One question: I followed the tutorial and it came out fine except that the list wouldn't retain the entries. However, I did not do this as a standalone app - I added the todo list as an activity to an existing app I'm making. Would that be the reason the entries disappeared once I closed the activity and went to another page? Maybe there's a bit of extra code I'm needing?
Thanks again for the tutorial. Really helpful for a 50+ lady like me who's such a rookie
listen in at the beginning he said that nothing will be saved on app exit I think
make me realize how easy swift is building an app.
Please, bring on flutter tutorial Brad.
great suggestion
